IAR Visual State is a set of tools for designing, testing and implementing embedded applications based on state machines.
It allows you to build your design from a high level, structure complex applications, and then step by step add functionality at a more detailed level. IAR Visual State is a powerful tool that can be used stand-alone. Using the tool together with IAR Embedded Workbench brings out several unique features, such as true state machine debugging.
The Navigator is used for the overall handling of your embedded development project. From here, you can launch the other modules of IAR Visual State and you can specify settings for the Verificator and the Coder. The Navigator contains a tree browser where you can see the file structure of your workspace. A workspace is a file that contains one or more projects with systems and state chart files.
The Designer is a state-of-the-art tool for designing state machines. The tree browser allows you to overview and navigate through your embedded project. All elements of the system are visible and accessible through the browser, and a double-click on the desired element brings up the appropriate configuration dialog box on the screen.
To find out whether your state machine design behaves as intended, you use the Validator. You test and validate your application by sending events into the design model, and in the different windows you can see the results of the events. The validator can also use the Designer to animate the applications response directly on your state machine diagram.
The IAR Visual State Verificator utilizes formal verification methods and combines them with a highly efficient abstract internal representation of the system; thus drastically reducing the time and memory consumption normally associated with formal verification techniques. By using the Verificator, you can discover design mistakes early.
The prototyping concept of IAR Visual State makes your communication with marketing and customers much easier. It will help you increase the awareness and knowledge of your product before it is launched. Your sales force and technical support staff will already be well acquainted with the product and able to introduce the product on the market rapidly.
Ability to design models using local transitions which for some models simplify the designs.
Support for letting a choice state be the target of the default transition to simplify initialization based on e.g. guard conditions that rely on external values.
Ability to get the current state tree for a VS system by the function VSGetCurrentStateTree.
Support for variants
Ability to model and build different variants from the same Visual State model to more easily handle different design variations for features depending on things like geographical region, feature differentiation etc.
Hierarchical Coder
Hierarchical Coder (HCoder) added. The Hierarchical Coder can improve the code size and speed efficiency for some models by better utilizing the hierarchical information in the models. The HCoder does not replace the current classic code generator, but is a complement.
Improved MISRA C/C++ compliance
The MISRA C:2012 compliance of the generated code has been improved.
64-bit applications
The Visual State applications are now 64-bit applications. This will increase the Verificators ability to handle larger models.

The evaluation edition is intended for prospective customers to test and evaluate IAR Visual State, and must not be used for product development or any other kind of commercial use.
“Our main challenge before purchasing products from IAR Systems was to manage very complex priorities and animations in HMI systems. IAR Visual State provides us with a powerful graphical tool that handles these priorities and delivers fast and reliable executions on embedded systems.”
With IAR Visual State, Schneider Electric gets consistent semantics applied to all state machines with code generated automatically. This makes a big difference to the company since it significantly saves development time.
As a contract developer of medical devices, Sunrise Labs must clearly communicate a detailed design with its clients, device users, developers, and risk management teams. IAR Visual State provides an excellent mechanism to communicate designs, and the confidence that once this design is understood and approved, it is implemented with perfect fidelity. The new statechart Viewer application in IAR Visual State makes this process especially convenient.
